Pre-engineering for ten large-scale biomethane projects across five countries
13 July 2026
Before a biogas plant breaks ground, a substantial amount of engineering work happens behind the scenes. This is the pre-engineering phase, or FEED (Front End Engineering Design). It is the stage where our engineers translate a client's ambitions into a detailed technical basis for realisation, covering process design, equipment selection, plant layout, and project economics.
Right now, HoSt's biogas team is running FEED studies for multiple projects spanning amongst others; Ukraine, Germany, Spain, Norway, and the United States.

Some examples of FEED studies being carried out by HoSt Bioenergy Systems
- In Ukraine, four manure and agricultural residue-based plants are in preparation, with individual inputs ranging from 130 to 250 kton per year and biomethane outputs between 4 and 6 million Nm3 per year.
- In Germany, two projects are being engineered, each processing around 120 kton per year of manure through multiple industrial digesters, targeting approximately 4 million Nm3 per year of biomethane.
- In Spain, a project combining manure and sludge at 140 kton per year is designed to produce 5 million Nm3 per year.
- In Norway, a facility processing 200 kton per year of manure, fish waste, and food waste will include a depackaging installation and CO2 liquefaction, with a target output of 7.5 million Nm3 per year.
- In the United States, a large-scale manure-only plant with 600 kton per year input is being engineered to deliver 12 million Nm3 per year of biomethane.
Project capacities
Combined, these projects represent approximately 2.3 million tonnes of organic input per year and a total biomethane production capacity of around 60 million Nm3 per year. All are planned for realisation within the next two to three years.
The scope and diversity of this pipeline reflects the growing global demand for industrial-scale biomethane infrastructure, and the trust that clients across the world are placing in HoSt’s engineering expertise.
